The Meinl Sonic Energy Solid Kalimba is a wonderful melodic instrument with unique characteristics, not only in sound but also in design. It features 10 notes in the C Major scale (e', c', a, f, d, c, e, g, b, d') and is made of high-quality maple wood. The traditional hole of this kalimba creates warm tones and longer sustain in sound. This kalimba comes with a case, a microfiber cloth for cleaning, and a tuning key.
